MySQL Data Manager is a generic web front-end for MySQL databases. More interesting than that, it's a commercial product written in Perl and using timbot (Bunce)'s excellent DBI module. It's not often I see new commercial Perl software, so I'm glad it's still being produced.
Here are two web sites I've recently enjoyed (warning: minimal Perl content ahead:-):
lileks.com. Hilarious rips on images from the US of the 50s and 60s.
half.com.
Lots of cheap music, books, and DVDs. I've been on an
Irish music bender recently, and I've found a lot of
stuff I was after for $3 to $8.
